metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...
In this paper, a new computational model with appropriate specifications is presented for finite element analysis of local stresses at the intersections of longitudinal stiffeners with transverse frames under lateral loads in ship’s side structures. Because of the importance of such locations for fatigue analyses and also the dependence of these analyses on the maximum stress values at cr...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
in this paper the critical strain energy release rate for t300/913 carbon-epoxy laminated composites has been studied using ansys finite element software based on virtual crack closure technique ( vcct ). compact tension ( ct ) specimen has been used for numerical analyses and the geometrical dimensions have been extracted from the existing references. the results obtained from the finite eleme...
SUMMARY This article presents an overview of eigenproblems that arise in current nite-element computations. We focus on a set of applications that have been studied at CERFACS, Centre Europ een de Recherche et de Formation Avanc ee en Calcul Scientiique, and describe the ideas and tools that have been developed to deal with them. The main characteristics of ve diierent cases are given. We also ...
To investigate buckling/ultimate strength of ship bottom plates, a series of elastoplastic large deflection analyses is performed applying finite element method. To achieve this purpose, symmetrical conditions are imposed on the plate boundaries. Also a series of elastic large deflection analyses is done in order to assess buckling behaviour and strength of continuous plates under combined late...
